Maybe you already are familiar with this but I actually find Nuendo to be a bit more flexible than Pro Tools in this regards since Nuendo lets you drag mono files onto stereo tracks and for me is a wonderful middle ground between Logic and Pro Tools. Pro Tools forces you to have stereo files and doesn’t let you change the panners function between the balanced and stereo. Logic just gives you a balanced panner when it is stereo and makes you use a somewhat confusing plug-in if you want to steer the sound in stereo.
Perhaps there is a preference or something that might solve the problem to just be able to drag the files as you want them on to stereo tracks, I use that too in Pro Tools. Check out the screenshot(s) these are options not found in Pro Tools or Cubase that would be very nice to have.
